Measurement of -hadron branching fractions for two-body decays into charmless charged hadrons

LHCb collaboration, R. Aaij, C. Abellan Beteta +589

Based on data corresponding to an integrated luminosity of 0.37 fb^-1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: B(B0 -> pi…

Observation of CP violation in B+ to DK+ decays

LHCb collaboration, R. Aaij, C. Abellan Beteta +589

An analysis of B+ to DK+ and B+ to Dpi+ decays is presented where the D meson is reconstructed in the two-body final states: K+pi-, K+K-, pi+pi- and pi+K-. Using 1.0 fb-1 of LHCb d…
